PIPE

Filed April 8, 1926 INVENTOR BY M A TTORNE Y Patented Apr. 29, 1930UNITED EST areas EUGENE LUCAS, 0F BABYLON, NEW YORK PIPE Applicationfiled April 8,

This invention relates to a tobacco pipe.

In smoking the usual form of pipe comprising a bowl and a stem with ahole through the stem to the bowl, the smoker'finds that the bowlbecomes hot and thehole in the stem clogs up. In addition, after aperiod of time the pipe cakes and unless the cake is cut out eventuallycauses a breakage of the bowl.

One of the objects of this invention is to decrease the temperature. ofthe outer walls of the bowl. Another object of the invention is toprevent radiation of heat to a smoke well below the tobacco bowl. Stillanother object of the invention is to provide a pipe that will smokesatisfactorily at a low cost of manufacture. A further object of theinvention is to provide a'pipe that can be easily cleaned and one thatwill not cake although smoking in a cool manner similar to a well cakedpipe. Still other objects of the invention are to provide a pipe thatwill retain the heat within the inner bowl to more entirely consume thetobacco and be sanitary at the same time and give a cool, clean smoke.

Referring to the drawing:

Figure 1 is a longitudinal sectional view partly in elevation embodyingthe principles of my invention.

In carrying out my invention, I propose to make the bit preferably ofhard rubber although any of the well known materials of which pipe bitsare made can be used. A hole or smoke conduit 2 is drilled therethroughin the usual manner and bit 1 is preferably made tapered as at 3 to fitwithin the protruding stem 4 from the pipe. I also propose to make thepipe proper of clay which comprises an inner bowl 5 terminating at thetop in a collor 6 and having a passage 7 from the bottom thereof tosmoke well 8. Adjacent bowl 5 is bowl 9 made principally of magnesium.Around bowl 9 is the pipe body 10 formed of two parts, 10 andlO. Thebody part 10, contains within itself bowls 5 and 9. The three bowls 5,9, and 10, are pressed into an integral'unit while in a plastic stateand then glazed or vitrified both inside and outside to make the unitnon-porous. The lower part 10 is likewise glazed or vitrified to make itnon-porous. The lower portion 10 contains 1926. Serial No. 100,484.

smoke well 8 and pad 11 which may be of antiseptic material. The lowerportion 10 is made integral with the stem 4. tion 10' and lower portion10 together at 12.

The inside of bowl 5 is preferably glaze-cl to prevent burning orcharring and its satura tion with nicotine. It will be noted that suchconstruction prevents the formation of heels of saturated tobacco or theformation of cakes in the bowl. 7

The inner bowl 9 of magnesium reduces the radiation and transfer of heatfrom bewl 5 to the outer portions 10, 10", and smoke well 8. 7

Smoke well 8 not only operates as a coolingchamber, but also preventsmoisture from the mouth from reaching the tobacco and such moisture isabsorbed by pad 11. The glazing of the walls of smoke well S'preventsthe abare threaded Upper porsorption of moisture making the pipe moresanitary. I

The tobacco burning in bowl 5 radiates the majority of its heat outofthe top of the pipe giving a more satisfactory smoke. The clay pipe canbe colored or decorated exteriorly with artistic designs and glazed ifdesired.

It will thus be seen that I have invented a pipe that can be readilycleaned by the flushing with water or, if desired, can be taken apartand easily cleaned and one that is cheap to manufacture, giving asatisfactory, pure, clean and cool smoke.

What I claim is:

1. A claypipe comprising a bit, a stem and a bowl, said bowl formed intoan integral unit from three bowls while in a plastic state, said bowlcomprising an inner clay bowl glazed on the inside, an outer clay bowlglazed on the outside, a magnesium bowl between said inner and outerbowls, a smoke passageway from said inner bowl through said outer bowl,stem and bit.

2. A clay pipe comprisingin combination a bit, a stem, a body portionformed in the plastic state of three bowls into an integral unit andglazed internally and externally, said body portion consisting of aninner bowl, an outer bowl, and a lining between said inner and outerbowls of heat insulating material.

3. A clay pipe comprising a bit, a stem and a body portion, said bodyportion separable from said stem and adapted to be threaded therein,said body portion formed in the r" plastic state into an integral unitof three bowls, said bowls comprising an inner bowl and a bowl of heatinsulating material between said inner and outer bowls, said bodyportion glazed internally and externally,

said stem glazed internally and externally, a

smoke passage between saidbody portion and said stemrand a smoke passagethrough said stem and said bit.

4:. A clay pipe comprising a bit, a stem and a bodyportion, said bodyportion separable from said stem and adapted to be threaded therein,said-body portion formed in the plastic state into an integral unit ofthree bowls,'said bowls comprising an inner 0 bowl and a bowl of heatinsulatingmaterial between said inner and outer bowls, said body portionglazed internally and externally, a smoke well in said stem, a smokepassage from said body portion to said smoke well,

a smoke passage through said stem through said smoke well communicatingwith a smoke passage in said bit, said stem glazed internally andexternally.

5. A clay pipe comprising a bit, a stem and a body portion, said bodyportion separable from said stem and adapted to be threaded therein,said body portion formed in the plastic state into an integral unit ofthree bowls, said bowls comprising an-inner ii-owl, an outer bowl and abowl of heat insulating material between said inner and outer bowls,said body portion glazed internally and externally, a smoke well adaptedto receive an asbestos pad, an asbestos pad 7 for said smoke well, asmoke passage from said body portion to said smoke well, a smoke passagefrom said smoke well through said stern and communicating with a smokepas- V sagein said bit, said stem glazed'internally and externally.
